1000Base SFP Module for 10km Singlemode Fiber

The VERSITRON GB10SFB is a 1000Base SFP module designed to extend Gigabit Ethernet connectivity over singlemode fiber distances up to 10 kilometers.

The module uses 1550nm for transmission and 1310nm for reception, providing complementary wavelength operation with the GB10SFA. This makes the GB10SFB an effective solution for long-distance Gigabit Ethernet links where a singlemode fiber connection is required.

According to the VERSITRON Fiber Optic SFP Modules datasheet, the GB10SFB provides 1000Mbps operation over 10km of singlemode fiber with an LC connector and is rated for operation from 0°C to 70°C.

Long-Distance 1Gbps Fiber Connectivity

The GB10SFB combines Gigabit Ethernet performance with a 10km singlemode fiber reach, allowing network designers to extend Ethernet connectivity beyond the distance limitations of copper cabling.

Its LC fiber interface provides straightforward integration with compatible SFP-enabled network switches, media converters, and other fiber networking equipment.

The industry-standard SFP form factor also allows the module to be installed or replaced without replacing the entire networking device. VERSITRON SFP modules feature hot-pluggable operation, a 3.3V power supply, and TTL signal detection.

GB10SFB and GB10SFA: Complementary 10km SFP Modules

The GB10SFB and GB10SFA are complementary wavelength SFP modules designed to work together for long-distance Gigabit Ethernet fiber links.

The VERSITRON datasheet lists both modules as 1000Mbps, 10km singlemode SFPs with LC connectors, with their transmit and receive wavelengths reversed.

For a complementary wavelength connection, install the GB10SFA at one end and GB10SFB at the opposite end of the fiber link.

GB10SFB Technical Specifications

These specifications are based on the VERSITRON Fiber Optic SFP Modules datasheet.

Typical Applications

The GB10SFB is well suited for network applications requiring 1Gbps connectivity over extended singlemode fiber distances.

• Enterprise Networks – Extend Gigabit Ethernet between network locations and facilities.
• Campus Networks – Connect buildings and remote network equipment over singlemode fiber.
• Telecommunications Networks – Support reliable fiber connectivity within telecom infrastructure.
• Industrial Networks – Connect remote equipment while avoiding the distance limitations of copper Ethernet.
• Government Networks – Extend network connectivity between buildings and facilities.
• Security and Surveillance Networks – Connect IP-based security equipment over fiber.
• Network Backbones – Provide Gigabit fiber connectivity between compatible switches and network equipment.
• Remote Site Connectivity – Extend Ethernet service to locations up to 10km away.

Industry-Standard SFP Design

The GB10SFB uses an industry-standard Small Form Pluggable (SFP) design with an LC fiber connector. VERSITRON SFP modules incorporate differential LVPECL inputs and outputs, a single 3.3V power supply, a TTL signal detect indicator, and hot-pluggable operation.

The modules also use a Class 1 laser compliant with EN 60825-1.

Selecting the Right 1000Base SFP Module

VERSITRON offers Gigabit SFP modules for different fiber types, wavelengths, and transmission distances, including multimode and singlemode options. The product family also includes complementary wavelength SFP modules for long-distance fiber connections.

When selecting an SFP module, consider:

• Data rate – Select the required 100Mbps, 1000Mbps, or 10Gbps module.
• Fiber type – Determine whether your network uses multimode or singlemode fiber.
• Transmission distance – Select an SFP rated for the required fiber distance.
• Wavelength – Match the wavelength requirements at both ends of the connection.
• Connector type – VERSITRON SFP modules use LC fiber connectors.
• Complementary module – For complementary wavelength operation, make sure the transmit wavelength of one module corresponds to the receive wavelength of the other.

For the 10km complementary wavelength pair:

• GB10SFA: 1310nm Tx / 1550nm Rx
• GB10SFB: 1550nm Tx / 1310nm Rx
